Final answer:
To find the percent strength of the diluted solution, calculate the amount of solute in the original solution, and then calculate the percent strength in the diluted solution.
Step-by-step explanation:
To determine the percent strength of the diluted solution, we need to know the initial concentration and the final volume. In this case, we have a pint of 25% (w/v) solution, which means there are 25 grams of solute (in this case, it could be a solid dissolved in a liquid) in 100 mL of solution. Since a pint is equivalent to 473.18 mL, we can calculate the amount of solute in the pint:
25 grams/100 mL x 473.18 mL = 118.30 grams
Now, if we dilute this solution to 1 L (1000 mL), we can find the percent strength of the diluted solution:
118.30 grams/1000 mL x 100 = 11.83%
